A2A SHIB Payment System - OpenClaw Skill

Framework-agnostic agent-to-agent payment infrastructure on Polygon network.

Summary

This skill enables AI agents to: 💰 Send/receive SHIB payments on Polygon (~$0.003 gas) 🔒 Create trustless escrow contracts 💬 Negotiate prices automatically (multi-round) ⭐ Build reputation through ratings 🌐 Discover other agents via A2A protocol 9,416x cheaper than traditional escrow services (Escrow.com charges $28.25 per $100, this costs $0.003).

Payment System

Direct SHIB transfers on Polygon Sub-penny gas costs (~$0.003) Balance checking Transaction history

Escrow System

Time-locked trustless payments Multi-party approval required Delivery proof submission Automatic release when conditions met Dispute resolution with arbiter 6-state machine: pending → funded → locked → released/refunded/disputed

Price Negotiation

Service quote creation Multi-round counter-offers Accept/reject workflow Automatic escrow integration Service delivery tracking

Reputation System

Star ratings (0-5) with reviews Dynamic trust scores (0-100) Trust levels: new → bronze → silver → gold → platinum Achievement badges Agent verification

Security Layer

API key authentication (64-byte keys) Rate limiting (requests + payments + volume) Immutable audit logging (hash-chained) Per-agent permissions & limits

Installation

# Via ClawHub clawhub install a2a-shib-payments # Or manual clone cd ~/clawd/skills git clone https://github.com/marcus20232023/a2a-shib-payments.git cd a2a-shib-payments npm install

Configuration

Create .env.local: cp .env.example .env.local nano .env.local Required environment variables: WALLET_PRIVATE_KEY - Your Polygon wallet private key RPC_URL - Polygon RPC endpoint (default: https://polygon-rpc.com) SHIB_CONTRACT_ADDRESS - SHIB token contract (default: 0x95ad61b0a150d79219dcf64e1e6cc01f0b64c4ce)

Start the Agent

node a2a-agent-full.js Agent runs on port 8003 by default.

OpenClaw Integration

The agent exposes A2A protocol endpoints that OpenClaw can communicate with: Agent Card: http://localhost:8003/.well-known/agent-card.json Example commands from OpenClaw: // Check balance const result = await fetch('http://localhost:8003/a2a/jsonrpc', { method: 'POST', headers: {'Content-Type': 'application/json'}, body: JSON.stringify({ jsonrpc: '2.0', method: 'message/send', params: { message: { kind: 'message', messageId: '1', role: 'user', parts: [{kind: 'text', text: 'balance'}] } }, id: 1 }) }); // Send payment // text: 'send 100 SHIB to 0x...' // Create escrow // text: 'escrow create 500 SHIB for data purchase payee data-agent' // Check reputation // text: 'reputation check data-agent'

Framework Compatibility

Works with: ✅ OpenClaw - As a skill or standalone agent ✅ LangChain - Via A2A tools ✅ AWS Bedrock - Via agent invocation ✅ AutoGen - Via A2A messaging ✅ Any A2A-compatible system See INTEGRATION-EXAMPLES.md for detailed integration guides.

Data Marketplace

// Research agent buys Tesla historical data const quote = await negotiation.createQuote({ service: 'TSLA 2020-2025 historical data', price: 500 // SHIB }); // Counter-offer and accept await negotiation.counterOffer(quote.id, 'research-agent', 400); await negotiation.acceptCounter(quote.id, 'data-provider'); // Escrow created automatically

AI Model Training

// Create escrow for model training job const escrow = await escrowSystem.create({ payer: 'startup-agent', payee: 'ai-trainer', amount: 1000, purpose: 'Train GPT-style model', conditions: {requiresDelivery: true}, timeoutMinutes: 720 // 12 hours });

A2A Protocol

/.well-known/agent-card.json - Agent capabilities /a2a/jsonrpc - JSON-RPC messaging /a2a/rest/* - REST API
